When to help a stoat or weasel;
If you are certain it is orphaned
If you can see that the nest chamber is totally destroyed, for example, dug up or flooded out completely then the Kits must be taken in. If you find very young kits above ground then there is a problem, Stoats and Weasels don't open their eyes for some weeks and will not venture out of the nest. Search the area to see if there are any more and contact your nearest wildlife rescue centre.
If the Stoat/Weasel has open wounds
Open wounds can become infected and may not heal without assistance. In the hot weather it is especially important for injured animals to be picked up as they may be suffering from 'fly-strike'. Flies lay eggs on sick or injured animals which hatch into maggots and eat them alive. If you see what look like tiny grains of rice, or grass seeds it is very important the Stoat/Weasel receives care as soon as possible.
If caught in a snare or trap
Cut out but do not release.
Once the Stoat or Weasel has been freed it must be taken to a wildlife rescue centre. Even if there are no visible injuries the flesh may start to break down several days later in a process called pressure necrosis. Any animal caught in a snare/trap must be observed for at least seven days before being re-released.
